Analysis and simulation on measurement error of costas loop

摘要

In receiver design, how to choose the loop phase detector and loop filter carrier tracking loop is critical. Due to the Doppler frequency difference uncertainty exists, the carrier phase direct capture a greater degree of difficulty, and the frequency was able to capture most quickly eliminate the Doppler shift of the impact, and then the tracking phase is relatively easy to get many. Based on this idea, this paper, the performance of the PLL comprehensive analysis and simulation.
